Antenna mounted in attic? (self.amateur_radio)

How poorly would an attic mounted antenna perform? Obviously worse than something outside, I'm guessing, but how much worse?

My office has one of those "side attics." It has a half sized door. Mounting a long antenna in there is very tempting because of how much easier it would be than doing anything outside. It's on the second floor as well.

In my attic, I have an Open-Stub J Pole and a 20m dipole. They work pretty well! You'll need to make sure that you don't have a metal roof or any foil layers in the roofing or insulation. If you're running a dipole, try to avoid electrical wires -- if you can't, have the dipole cross them at a 90º angle.

I was thinking about putting my 2m antenna in the attic, I didn't think about metal though. I have asphalt shingles but I have solar panels basically covering the south face. I'm guessing the brackets, panels, and wiring will all add up to my plan not panning out well.

Solar panels, specifically inverter is likely to generate a lot of noise
